IMPROVEMENT IN CORN -PLANTERS.

Specification forming part of Letters Patent No. 30,446, dated October16, 1860.

To an whom it may concern Be it known that I, J. W. HARBIN, of DelawareStation, in the county of Ripley and State of Indiana, have inventedcertain new and useful Improvements in Seed-Planters; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being bad to the accompanying drawings, and to theletters of reference marked chanical arrangement of devices foroperating the agitator and the slide of the seed-hopper. A is the frameof the machine; B is the hop per or seed-box, and G G are handles, whichare attached to the forward part of frame A,

and supported by the supports or standards E E, as shown.

D is a presser or traction wheel, upon which are small projections a a,and these act upon and operate the lever 11, thereby communicatingmotion to the slide K in the interior of the, hopper. The lever b ispivoted to a standard, F, and near the standard is connected with tworods, 0 d, by means of a link. The rod 0 communicates motion to theagitator 9, being connected to a crank which is attached to theagitator. A small spiral spring, I, is placed under the end of the leverb, and is attached to said lever for the purpose'of throwing it back inthe same position it was beforepassing the projection on thetraction-wheel D.

H is adouble share, for the purpose of forming the furrows in the groundfor thereception of the seed. It (the share H) is provided with a numberof peculiarly-formed wings or coverers, f f, arranged vertically uponits diverging sides, as shown in Fig.1, said wings serving the purposeof pulverizing the earth displaced by the front end of the share, and

returning fine earth to the furrow, so as to cover therewith the seedwhich has been deposited in the furrow.

g is the agitator, operated by the rod 0, and serves to keep the seedfrom arching over the small aperture in the hopper by which it would beprevented from falling into a small chamber, h, from which it isdelivered into the tube h, and thence tothe ground.

The slide K is provided with a U-shaped spring, 6, which forces theslide forward, letting the seed which may be contained in the chamber71/ descend the tube It to the ground the moment the lever 1) passes oneof the projections a a on the surface of the tractionwheel D. This slidehas an adjustable plate, It, on the upper surface for the purpose of in-{creasing or diminishing theaperture through which the seed passes fromthe seed-box into the small chamber h. The plate It is adjusted toregulate the size of the aperture into the small chamber It by thescrewy, which passes through the end of the plate It and into the slideK, thereby adjusting the aperture, as described.

The hopper B is of rectangular form, and is made as shown in thedrawings.

G is the draft-beam by which the machine is drawn.

The object of my invention is to produce a seed-planter which is simplein its construction, and which, having deposited the seed at equaldistances in a furrow, eovers it properly with pulverized earth, andthen compresses the earth upon the seed to a suitable degree.

The operation of my machine is as follows: The seed to be planted havingbeen placed in the hopper and the machine being drawn appropriately overthe ground, the share 11 entore the earth, forminga furrow of a suitabledepth. The roller D, being in contact with the ground, is caused torotate, and one of the projections a, encountering in its revolutionsthe lever b, depresses it and communicates motion to the slideK andagitator g by means of the connecting-rods c d, thereby causing,

the seed to descend the tube It and enter the furrow. The wings orcoverers f return the fine earth which has been thrown out by the shareH, and covers the sed. ,The roller 1) passes over the ground andslightly com? presses it.

Havingdescribed myimproved seed-planter, what; I claim as my invention,and desire to secure by Letters Patent, is i The arrangement of thespring-lever-b stip- 1gortved by thestandard F, and operated by theroj'ecfiing pins a, a upen the traction-wheel D,

in connection with the redd', operating the spring-slide K, and therod0, operating the agitator g, in the manner as and for the purposes setforth.
